To succeed in tech, you must be a master of innovation. No two companies understand this better than Apple and Google, which have become kings of the industry thanks to a string of incredible ideas that have shaped the technology we rely on today.

But which company is continuing to innovate in 2015? Is it Apple, with its fitness-focused Apple Watch, Apple Pay, and a new streaming service that hopes to save the music industry? Or is it Google, with Google Glass, self-driving cars, and secret robots?

Google has begun integrating its notification center into Chromium for Mac, paving the way for Google Now for OS X. The Chrome OS feature was first ported to Chromium and then Chrome Canary for Windows back in March, but this is the first time it has been spotted on Mac.

Google Now, the intelligent personal assistant that was introduced to Android 4.1 Jelly Bean last June, appears to be gearing up to make its debut on iOS. The feature will be integrated into the Google Search app for iPhone and iPad, according to a promotional video that was allegedly posted to Google’s official YouTube channel prematurely — before quickly being pulled again.
